JKent Posted November 7, 2008 Report Share Posted November 7, 2008 Just bought my first pair of Advents--originals with the 10" Masonite-ring woofers. Any tips would be appreciated. Although I have refoamed AR and Allison speakers, these are new to me.Pete B has been generous with his advice but I know he's pretty busy now and I have LOTS of questions, so I'm posting them here.I know some people don't use shims, but my usual supplier, M-Sound, gives good arguments FOR shims. OTOH Pete, who has worked on Advents, writes "the LA woofer has to play up into the lower midrange and the dust cap is critical" so "don't cut the dust cap - these have lots of clearance easy to do by feel or with a test tone". That makes sense, too.Pete also recommends "very high compliance foam". I asked M_Sound about that and got this reply: The new foams have a larger roll, which look fairly large... although when measured (from the rear), are only 5/8" across but are fairly deep (which was what our main complaint about the old foam was). In any case, IF you glue them to the back of the fiber spacer, I hear they tend to look "right." Any comments?Pete also suggested "you might want to replace the inductors with air core." Do the Jantzen 20 ga inductors from Parts Express look like a good choice?http://www.parts-express.com/mfg/jantzen/jantzen.cfm#15gaugeAlso, M_Sound tells me " I am offering now that is great for these old classic speakers, is bypass caps for your tweeters' crossover capacitors. I offer them at an extremely attractive price; TWO for $2.00! They're metallized polypropylene 0.10uF 400V; perfect for bypassing your Tweeters' crossover caps."Ideas concerning bypass caps?Finally, in an earlier thread Pete wrote "Put a .47 ohm 5W resistor in series with the new caps to approximate the ESR of the original electrolytics". Would that be on BOTH the woofer and tweeter? I'll probably use some Dayton polys I have on hand.thanksKent Link to comment Share on other sites More sharing options...
